GATE CONSTRUCTION.

.iaiaisa;

To all whom it may concern:

Be it known that I, CARL C. CAMERON,-2lcitizen of the United States, residing at Slater, in the county of Saline, State of Missouri, have invented certain new and useful Improvements in Gate Constructions, of which the following is acomplete specification.

The present invention relates to gate structures, and one of the objects in view is to provide a novel form of gate supporting means whereby the gate frame is allowed not only a pivotal swinging movement'about its fixed supporting axis but also a swinging movement about an axis intermediate the sides of the gate frame. i

To this end I have devised a hanger supporting member which is mounted'upon a fixed supporting axis and also pivotally connected with the gate frame for suspending the latter for pivotal swingingmovement about a vertical secondary axis which shifts in accordance with the position of the .gate frame. j

A further object is to provide a gate structure havinga hanger supporting member of the character described and also including provision for limiting the swinging movement of the gate about its secondary or shifting axis in one of the directions of said movement. V

Incidentally it is sought to devise a novel gate construction with. particular reference to stock chutes for the loading or unloading of cars with a view to providing a safe, convenient and efiicient gate arrangement for closing the sides of the passageway across the platform from thechute to the car. lVith these general objects in view to the accompanying drawing illustrating a practical form of constructlon which has been devised 'for embodying the proposed Application filed April 7,

the invention will now bedescribed with reference Specificati'cnof Letters Eatent. Patented Apr. 18, 1922.

1919. Serial No. 288380.

occupying the same position as in Figure 1, with broken lines illustrating another po sition of the gate; 7

- Figure 3 is a section taken on the line 3-3 of Figure 1; V

Figure 4 is a perspective view of one of the gates; and v F1gures5 and 6 are side and edge views, respectively, of a modified form of the gate construction. 7

Referring to the drawing i-n detail, this shows 1n Figure 1 the floor. 8 of a stock chute lead-ing toa platform 10, across which stockis passed in being unloaded from'or loaded into a car 12. The chute hasthe side walls 1 1, and to the posts 16 at the edge of the platform 10 are secured pintles 18 for the pivotal mounting of gate hangers 20rfor swingingmovement about vertical fixed axes at the opposite sides of the chute.

Fach hanger 20 of general U-shape, hav' ing the terminaleyes 22 for fitting over the pintles 18, and the. vertical or intermediate portion of the hanger is'pivotallyc'onnected to the top and bottom cross pieces 24 ofone of the gate frames; by means of brackets 26.

These brackets 26are located intermediate the sides ofithegate frame, whereby the lat.- ter swings in the hanger about a vertical tical rod or connection 28 joining the upper and lower arms of the hanger; this vertical rod is in position to form a stop for engagement with the gate frame (as by engagement with one of its vertical side pieces 30) for the purpose of limiting the swinging movement of the gate and preventing that side of the gate from passing on through the space between the fixed and movable gate axes above described. It will also be noted that the horizontal leg portions of the hanger are. of bent or angular form and of a length permitting the gate to swing to such an extent as to bring one side thereof into, a position intersecting a plane passing throughsaid fixed and movable axes, as shown in Figure 2, A modification of this stop means is illustrated in Figures 5 and 6, in which the vertical rod or connection between the arms of the hanger is omitted, and the side members 30 of the gate are extended to form projections 30 adapted to engage the arms of the hanger and thus limit the movement of the gate frame in the same manner as above de scribed. In either case the stop means serves to stop the swinging movement of the frame when the engaged side thereof comes into position intersecting a plane through the fixed and movable axes of the frame, with the plane of the latter at a slight angle with reference to the plane of said axes.

In the illustrated application or mode of use of the gate structure, the gate frame is of such width as to extend. across the platform 10 and project within the doorway of the car with the outer side members 30 of the gate frame resting against the jambs 32 at each. side of said doorway.

A simple and practical form of gate structure is thus provided for carrying out the desired objects of the invention, and the improved construction has special advantages in the particular relation illus trated in the drawing. It is common practice to employ swinging gate frames for stock chute platforms, but to construct these gate frames of such width as notlto project entirely across the platform and to proporbracethe gates in-the desired position;

The purpose'of usingthese narrower gates is to 'cl'ear'the sides of the cars in ord'erto-V avoid damage beingfdone to the cars or,

the gates in the event of casual 'movement of the cars. But such damageis -not alto;

gether avoided by 'theuse ofthe narrower gate frames because of the fact that the common type of gate employed is mounted to swing about a single axis, and when an objectcollides with'it directly in line witli' its axis the gate is not permitted to swing; Consequently, when gates of this single piv-- oted type are unfastened and free to swing (as they commonly are, especially when not in use for loading or unloading) they frequently assume such positions with reference to the sides of the car as to be caught by objects projecting out from the car, and

often cause serious personal injuries to trainmen aboard the sides of the car in the path of the gates. The present improved gate avoids anyfpossibility of such damage or injury taking place, for the double pivoted movement allows the gate to swing freely in either direction, and in the case of a thrust edgewise against the gate it simply moves backward entirely out of the path of the object colliding with it. Therefore the gates may safely be projected enirely across the platform and into the doorway of the car, and thus form continuous and complete closures for the passageway across the platform, and in this position they require no braces or props for securing them against spreading outward toward passlng the ends of the platform. When the gates are not in use they are simply pushedbackward into theend of the chute, as're oresentedby the broken lines in Figure 2. referably, the upper pintles 18 are located slightly out of line .with the-lower pintles to swing toward and rest against the j a'mbs 32 or the walls 14, as the case may be.

While I have illustrated and described What have been'found to constitute simple and practical forms of embodiment of the in such a way as to cause the gates to tend improvements, I desire to reserve the right to make such formal changes or modifications as may fairly fall within the scope of the appended claims.

What I claim is:

1. A gate construction comprising a gate frame, a pivoted hanger provided with horizontal arms hingedly connected with one of the faces of said frame-for supporting the same for swinging movement about a vertical movable axis intermediate the ends of the frame and shifting with the oosition thereof and. also for swin in I 7 ZS b movement about an approximately vertical fixedaxls, the arms of SilldlltIlgGIbG- ing of a lengthsuflicient to permit swinging movement of said frame into a position that one end thereof intersects thelplane of the fixed and movable axes intermediatesaid aXes, and stop means operativeto limit said swingin movement and'stop the frame at a slig t angle to said plane with] one end thereof in a positionv intersectingea plane passing through said fixed-and movable axes; and with the planeiof the frame at arslight angle with reference to; the. plane 7 0 f;

said axes;

' 2. A gateconstruction for stock chutes;

comprising a gate frame, and a pivoted hanger-supporting said frame for swing shifting with the positions" thereof, 'the' other of saidvertical rod portions of the hanger joining the bent portions of said arms and being adapted to engage the other face ofsaid frame and limit the swinging movement thereof about said first vertical rod portion of the hanger, the length of said arms being suflicient to; permit swinging movement of said frame into positio'nbringing one: end thereof into a line intersecting a plane passing-through said fixed and movableaxes.

In witness, whereof I afiix my signature;
